Brazilian jiu-jitsu. Brazilian jiu-jitsu (/dÊuËËdÊÉªtsuË/; Portuguese: [ËÊiw ËÊitsu], [ËÊu ËÊitsu], [dÊiËu dÊiËtsu]) (BJJ; Portuguese: jiu-jitsu brasileiro) is a martial art, combat sport system that focuses on grappling and especially ground fighting.
You can score points toward victory in both wrestling and BJJ, but competitors in both sports strive for a match-ending and match-winning move throughout the match. In wrestling, a fall ends the match if one wrestler holds the other on his back for three seconds. BJJ uses submission, which means one grappler has placed his opponent in a hold that hurts so much -- or threatens injury so certainly -- that he surrenders the match.
